Transform or extract the trajectories from the given object to a standardized format.
The standardized data format is for method estimation by latrend, and for plotting functions.
trajectories(object, ...)# S4 method for data.frame
trajectories(object, id, time, response, ...)
# S4 method for matrix
trajectories(object, id, time, response, ...)
# S4 method for call
trajectories(object, ..., envir)
# S4 method for lcModel
trajectories(object, ...)
The data or model or extract the trajectories from.
Additional arguments.
The identifier variable name.
The time variable name.
The response variable name.
The environment
used to evaluate the data object in (e.g., in case object
is of type call
).
A data.frame
with columns matching the id
, time
, and response
name arguments.
